To test real life performance of a drive we use a mix of folder/file types and by using the FastCopy utility (which gives a time as well as MB/s result) we record the performance of drive reading from & writing to a 256GB Samsung SSD850 PRO.
Transfer details:
100GB data file.
60GB iso image.
60GB Steam folder – 29,521 files.
50GB File folder – 28,523 files.
12GB Movie folder – (15 files – 8 @ .MKV, 4 @ .MOV, 3 @ MP4).
10GB Photo folder – (304 files – 171 @ .RAW, 105 @ JPG, 21 @ .CR2, 5 @ .DNG).
10GB Audio folder – (1,483 files – 1479 @ MP3, 4 @ .FLAC files).
5GB (1.5bn pixel) photo.
BluRay Movie – 42GB.
21GB 8K Movie demos – (11 demos)
16GB 4K Raw Movie Clips – (9 MP4V files).
4.25GB 3D Printer File Folder – (166 files – 105 @ .STL, 38 @ .FBX, 11 @ .blend, 5 @ .lwo, 4 @ .OBJ, 3@ .3ds).
1.5GB AutoCAD File Folder (80 files – 60 @ .DWG and 20 @.DXF).
The drive was pretty consistent when dealing with the larger file transfers in our real-life file transfer tests averaging 543.5MB/s writing six of the largest folders to the drive and 465MB/s when reading them back. The fastest transfer was for the 60GB iso image (551MB/s) with the slowest being the 50GB file folder transfer at 242MB/s.
To get a measure of how much faster PCIe NVMe drives are than standard SATA SSD's we use the same files but transfer to and from a 2TB Kioxia Exceria Plus drive:
Swapping over to an all NVMe architecture saw transfer speeds rocket as you might expect. Three of the write transfers topped 3GB/s; 60GB iso 3,100MB/s, 12GB Movie Folder 3,097MB/s and the 5GB (1.5bn pixel) image. 3,092MB/s. Seven more topped 2.5GB/s while the slowest was the 50GB file folder with 925MB/s writing and 530MB/s reading.
